actually Abraham is recorded to have much more than 3 sons ,but the most well known are Ishmael and Isaac.
Or maybe I've misunderstood and you're referring to Lincoln ,whose sons are:
Robert Todd Lincoln
Edward Lincoln
Willie Lincoln
Tad Lincoln
Sarah and Abraham had one child, a son, and named him Isaac.
Abrahams two sons are found in the book of genesis.
Sarah
Sarai
Abraham's second wife was Keturah, who bore him six more sons, one of who fostered the medianite tribes, these are the ones who lifted Joseph from the pit, selling him to the the Ishmalites(descendants of Abrahams first son by Sarah's handmaid), who then sold Joseph into Egypt.
Sarah Lincoln died when she was 21 Sarah Lincoln died when she was 21
Yes Sarah is very much a name from the bile,She was Abrahams wife, the mother of Isaac.
All of Abraham's sons died after he did.
he had a sister named Sarah and a bro named Thomas
Isaacs mother was Sarah, that is Abrahams wife.
Sarah Lincoln died from giving birth to her first child at the age of 21.
Abraham and Sarah had only one son, he was called Isaac and they got him in their very old age.
